Taxonomy
The name 'flounder' is used for several only distantly related species, though all are in the suborder Pleuronectidae (families Achiropsettidae, Bothidae, Pleuronectidae, Paralichthyidae and Samaria). Some of the better known species that are important in fisheries are:
Eye migration
In its life cycle, an adult flounder has two eyes situated on one side of its head, while at hatching one eye is located on each side of its brain. One eye migrates to the other side of the body as a process of metamorphosis as it grows from larval to juvenile stage. As an adult, a flounder changes its habits and camouflages itself by lying on the bottom of the ocean floor as protection against predators. As a result, the eyes are then on the side which faces up. The side to which the eyes migrate is dependent on the species type.
Habitat
Flounders ambush their prey, feeding at soft muddy areas of the sea bottom, near bridge piles, docks and coral reefs.
A flounder's diet consists mainly of fish spawn, crustaceans, polychaetes and small fish. Flounder typically grow to a length of 22–60 centimeters (8.7–23.6 in), and as large as 95 centimeters (37 in). Their width is about half their length. Male Platichthys are known to display a pioneering spirit, and have been found up to 80 miles off the coast of northern Sardinia, sometimes with heavy encrustations of various species of barnacle.
Threats
World stocks of large predatory fish and large ground fish, such as sole and flounder, were estimated in 2003 to be only about 10% of pre-industrial levels, largely due to overfishing. Most overfishing is due to the extensive activities of the fishing industry. Current estimates suggest that approximately 30 million flounder (excluding sole) are alive in the world today.pollution. In the Gulf of Mexico, along the coast of Texas, research indicates the flounder population could be as low as 15 million due to heavy overfishing and industrial pollution.
According to Seafood Watch, Atlantic flounders and soles are currently on the list of seafood that sustainability-minded consumers should avoid.
